"I usually put the deepest part of the concave between the feet. “The Sweet Spot.” “The Zone.”
I experimented with making the concave deeper in the center.
Then started moving it forward.
So, I moved the deepest part of the concave into the entry area.
Under the chest.
Added more tail rocker.
Very deep in the entry.
Paddled faster.
Got into waves quicker.
Held on turns yet still had a tight arc.
I blended it a little more. Gradual.
-.35 -.30 -.25
I have since done various depths on different existing models.
The SD RT RE has been highly rated by our team and customers who have either tried or purchased one.
The deepest part of the concave, in the entry, is .22 +-
It even works on longer boards, up to the mid to high
7-foot range.
Same concept, just shallower.
The Lowrider has also been very well received with a subtle Rapid Entry.
By having the deepest part of the concave in the entry, it feeds and keeps the water under the board early on and generates more lift and speed and drive.
